If wastewater line infrastructure is constructed on your road, and you already have an existing septic tank, then you can tie into the line at any time. However, if you choose not to tie in, and your septic tank has a catastrophic failure and must be redone, then you are required to tie into the new wastewater line. However, when tying into the new line you will need to fill out the proper forms. For more information please call our Utility Systems Engineer at (505) 891-5046.
